Application filed May 31,

This invention relates to improved means for fastening rails inlocations where the same must be secured to refractory material such asmasonry or brick structures which are subjected to abnormaltemperatures. .While, not limited thereto, the invention is well suitedfor use in securing the larry car rails to the top of a coke ovenstructure. The invention guard beam.

Referring in detail .to the drawings, 10 represents a body of refractorymaterial such as brickwork or masonry used in the construction of cokeovens. The coke oven is formed withthe usual buck-stays 12 which aretied across the top of the furnace by means of cross rods 14 having nuts16 thereon which engageplates or washers 18. 7

Rails 20-20 are secured, by my improved rail fastening device to behereinafter described, to the top of the coke oven so as to guide theusual larr car 22 used in carrying the coal which is to e chargedthrough openings' 11 leading to the coke chambers of the oven.

' Heretofore, it has been customary to secure the rails to the tie rods14. In practice this is objectionable because it restricts the freeexpansion of the rail due to the abnormal heat of the coke oven. Thisfrequently causes buckling or breaking of the rail and tends also totransmit objectional stresses to the tie rods and refractory material.

According to my improvement the rails 20-20 bear freely on pads orraised bosses of masonry 24 and the rails are held against displacementby clips 26 adapted to be engaged under the head of the rail asindicated inFig.

3 so as to abut the web 28 near the fillet joiningthe head to the web.Each clip 26 is provided with a base portion 30 which is seated on theupper surface of a beam 32 buried in the masonry and disposedsubstantially at right angles to the length of the rails. In theembodiment of the invention illustrated, the

beams 32 are formed of short sections of T- rail. The head 34 of eachbeam is notched at 36 and 38 for the reception of bolts 40 by means ofwhich clips 26 are secured in place.

As thus arranged, it is apparent that the clips 26 are effective tomaintain the correct gauge between the rails 20-20. Yet because of therelatively loose joint between the clips 26 and the web 28,. each railis freeto expand independently under the influence of the terrific heatof the coke oven. Thus, elongation of the rails due to the heat, orcontraction due to any change in temperature, will not set updestructive stresses in the oven structure. Each beam 32 as indicatedclearly in Fig. 4 is spaced from the bottom flange of the rail 20 sothat none of the load on the rails is transmitted tothe beams 32, thisload being transmitted to the pads or bosses 24 above referred to.

While 1 have described -quite specifically" the particular embodiment ofthe invention illustrated, it is not to be construed that I am limitedthereto since modifications may be made by those skilled in theartwithout departing from the invention as defined in the appended claims.

,What I claim is 1. A masonry structure formed with spaced integralbearing pads, rails seated thereon, means for positloning the rails onsaid structure comprising a beam whose top surface is below the level ofsaid pads and clips secured to said beam. a 2. A masonry structurehaving spaced bearsition with freedom to expand and contract withrespect to saidmasonry structure com-. prising transverse beams embeddedin the masonry and clips secured to said beams and having ofi'setportions spaced above the base flanges of the fail, the extremities ofsaid ing pads integrally formed thereon, rails clips being adapted toengage the web of the rail so as to prevent lateral displacementthereof.

4. A masonry structure having rails resting freely thereon, means forholding said rails against transverse displacement comprising beamsdisposed transversely of said rails and in said structure, bent clipshaving portions located in a plane immediately below the shaped to engae the web of the rail under bottom surface of said rails so as toprovide the head thereo and also having bearing por-' a clearance, andclips secured to said beams tions seated on said beam, the latterrbeing15 5 having ofiset web engaging portions spaced notched and boltsextending through the above the base flanges of the rail, notchedportions of the beams and engaging 5.
